Abstract (en)
@ Within an electronic device having a plurality of circuit parts (7...9) - such as a three-dimensional device - a light transmission system which transfers signals between the circuit parts by the use of light is provided, which is formed of a light emitting source (10, 11) which emits light having a desired wavelength, a photoelectric conversion portion (14, 15) which absorbs the light and converts it into an electric signal, and a light travelling part (12, 13) which conveys the light emitted from the light emitting source (10, 11) to the photoelectric conversion portion (14, 15). Each of the light emitting source (10,11), light travelling path (12, 13) and photoelectric conversion portion (14, 15) is formed of a superlattice structure in which a plurality of materials of unequal energy gaps are accumulated.
